Tips on first OC

[SlowEJ8]

Hey everyone, just did my first OC.
Currently on bios 1004, i think.

Check sig for my rig.

Currently using asus p8p67 M PRO b3 Revision

Overclocked- 4ghz @ 56°C Full load w/ Realtemp on Prime95 for 20 mins. CPU-Z reading 1.296v core voltage.

I'm not sure if I ran the test correctly, I just 'tested everything' for 20 mins.
Does this mean that its stable at this rate?
Or am i able to modify ATV and offset voltage in bios?
Seems like the temps might be a little too high, any comments?
thanks

Temps are perfect, at idle you should be around 47 or so. Some people obsess about lowering the temps. but anything under 70 is good and you are under that mark.

lowering the temps has to do with longevity, we replace parts faster than the higher temps will lower the life of the parts.

try linx as well, for a bit longer. 20 min of prime might not be enough, but it sounds like ur probably stable.

Voltage seems a little high to me. Maybe trying the offset voltage with a + 0.005v to see what it gets you. You might have to try a - 0.020v or something depending on what the board feeds the chip. My Asus board in sig needed a - offset for the baby overclocks 4ghz and under. For 4.2ghz the + 0.005v on mine gave me 1.291v under load. Voltage required will vary form chip to chip so YMMV and you'll have to do some stress tesing to make sure it's stable.

You should be peaking at no more than 1.25v at 4ghz.

This, +1.

OP when you said you did your first overclock how exactly did you do it?

 

[SlowEJ8]

Thanks a lot for the input guys, currently my cpu idles at 30°C on hottest core.
Heres what I did:

Ai Tuner: Manual
Internal PLL: Enable
Oc tuner: off
Turbo ratio: stock
Dram timing: stock
Cpu pwr management: ??
Cpu ratio: auto
Enh Intel SST: enable
Turbo mode: enable
turbo ratio: same as ai tuner(auto)
ATV: .004
Offset Voltage: .005
Dram volt: 1.5
vccio: 1.05
PCH: 1.05
LL Cali: disable
CPU SPCE: disabled
c13~ etc: all disabled.

Will updating bios allow a better oc?(or switching to a bios that will)
Ideally I want to get to at least 4.3ghz stable, with a lot of headroom. Or right now 4 ghz seems okay, but I'm worried about how high my vcore is.

I'm open to all comments and suggestions, thanks a lot guys!

Internal PLL: Disable

Lower offset voltage


From the looks of your sig, are you going to be switching to an Asrock Z68 Extreme3 Gen3? If so, I have some Bios settings that can get you started.

What are the increments I should be following to lower offset voltage?

If I can get a stable 4.3-4.5 with this mobo with low load temps, I'll just hang on to this instead.

UPDATE: I recently downloaded the 0708 bios and had that running, seems like it went better..


PLL is still enabled on this oc, same offset voltage
OC 4.2ghz @ 60°C on Full Load with a max of 1.296v running prime95(testing bits of everything), will get it running on another stress tester soon, any recommendations besides linx?
How do I know if I'm testing it right with prime95 anyway?

First oc questions:
Is the voltage suppose to spike while playing games?
And does anyone know a type of program that reads fps in game?

don't bother with linx. use p95 small ffts then p95 large ffts. linx always gives me a false sense of stability because stuff will be 20 pass stable with high memory use and crash with prime in 2 mins. I realize some people swear by it, but honestly it has been way too inconsistent for me to consider it a real stability test.

prime is easy to use. just select the torture test you want and run. it'll take care of the rest.

FRAPS can read FPS in games I believe.

The voltage should go up as the CPU goes from idle to load.

Ultimately you want to maximize your overclock and minimize your temps. Its up to you to find where the right balance is. Personally, an OC where I can keep the temps under <60 is fine for me. I currently run a 2600k at 4.4, with hyperthreading on and load voltage is around 1.26-1.28v. It idles in the low 20s.I could be more aggressive. I know it'll boot at 4.8-4.9 ghz if I wanted and 4.6 is stable with around 1.3 v, but I don't feel the need to be that aggressive (not much I run is CPU intensive and the 5 or 10 percent gain is something I don't lose sleep over). However, nothing is wrong with being more aggressive; like I said its up to you. Some people are comfortable with temps around 65 at full load, others even 70. The increments at which you jump around (ie adjust the offsets) again is up to you. I like to do increments of 2 at a time because it saves time as I narrow down the perfect voltage/setting/value, etc. The point of testing is to find the ideal settings for the goal you want to achieve. How quickly and methodically you get there again is up to you.

Overclocking is all about thermal management.

Not to hijack the thread but I just bought the Extreme 3 Gen 3 with a 2500k and would love those bios settings to get started OCing.

Update: Alright guys, Fiddelled around with the ATV and the offset voltage.

Ended up getting this setup to 4.5ghz stable 61°c on Full Load at 1.288v with intel burn test.

I hope I did this right, Was there anything else I was suppose to watch besides temp and voltage?

If not, thanks eveveryone for the help!

Looks good. My i5 2500K overclocked to 4.5GHz has similar temps on my P8Z68-V/GEN3.

Seems like a lot of people are able to get even lower vcore settings at high clocks and stable temps on full load.

What's your build you're using for your i5 2500k w/ p8p67 m pro?

Anyone know how to lower vcore on the p8p67 mpro ?
